This is how to make your own professional-seeming glass guitar slide from a bottle to get that nice bluesy sound, or to play any number of other types of music. This is a very easy method of making a great tool for guitarists, and makes great, cheap gifts for your guitarist friends.
Step 1: Gather Materials
One bottle. This should have a very pronounced neck, unlike some beer bottles which just taper slightly to the top. The project will work best if the neck on your bottle has a long, straight section, like a wine bottle.
Glass Cutter. If you don't have one, get one. I got mine for i think $3.50 at the hardware store, and its very useful if you're into DIY. This is essential to the project.
Sandpaper. You could rub the glass on the wet sidewalk, this also works. I use a combination, since the sidewalk is rougher than my sandpaper.
You may also want gloves, since there is a guaranteed potential for broken glass. hearing protection is also advised, since there is also a potential for loud noises.
